In a parallelogram wxyz , w and x are adjacent interior angles the measure of x is three times the measure of w which equation gives the exact measure of w

The required equation is .

Step-by-step explanation:

Given information: WXYZ is a parallelogram, W and X are adjacent interior angles and measure of X is three times the measure of W.

According to the properties of parallelogram, the two adjacent interior angle are supplementary angle and their sum is 180 degrees.

           .... (1)

It is also given that the measure of X is three times the measure of W.

Substitute this value in equation 1.

Substitute this value in equation 1.

Therefore the required equation is .

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
